How we score ranked profiles.
The BSU Score is a single 0–100 number. Here's exactly what goes into it — openly, reproducibly, and without any proprietary secret sauce.
Rating
The Google rating, scaled linearly from 0–5 stars to 0–40 points. A 4.5-star workshop gets 36 pts. A 3.0-star workshop gets 24.
Review depth
Log-10 scaled review count. 10 reviews = 10 pts, 100 = 20 pts, 1,000+ = 30 pts. This prevents drowning out honest small shops.
Completeness
3 points each for: phone, website, hours, main photo, and owner verification with BestServiceUAE.
Quality bonus
15 points at 4.5+ stars and 50+ reviews; 10 at 4.0+ and 20+; otherwise scaled by rating and review count.
From raw data
to final score.
Collect public business-profile data
The current snapshot was captured on April 8, 2026. It includes public ratings, review counts, categories, hours, photos, and contact details. This is not a live feed, so visitors should confirm current details before booking.
Calculate the rating score
Google rating translates linearly into a 0–40 point contribution. A perfect 5.0 earns 40 points, 4.0 earns 32, 3.0 earns 24, and so on. Unrated workshops contribute 0 here.
Measure review depth (logarithmically)
We use a log-10 scale for review volume, giving a maximum of 30 points. This prevents megacorps with 10,000 reviews from drowning out honest independent shops with 100 real ones. 10 reviews = 10 pts, 100 = 20 pts, 1000 = 30 pts.
Check profile completeness
Up to 15 points are awarded: 3 each for a phone number, website, published hours, a main photo, and owner verification with BestServiceUAE. Missing data lowers completeness but does not prove poor service.
Apply quality bonus
The quality bonus is 15 points at 4.5+ stars and 50+ reviews, or 10 points at 4.0+ stars and 20+ reviews. Below those thresholds it scales with both rating and review count.
Five honest tiers.
The score is 90 or higher under the published formula. This is a data tier, not a service guarantee.
The score is between 75 and 89. Compare recent reviews and obtain a quote before choosing.
The score is between 60 and 74. Check recent reviews and current workshop details before deciding.
The score is between 40 and 59, usually reflecting thinner review or profile data.
Insufficient data. Usually new workshops or ones with too few reviews to judge. Not "bad" — just unknown.
No games. No exceptions.
- We don't take money for rankings. Period. Not under any label.
- We don't include AggregateRating schema for thin data. If a workshop has fewer than 10 reviews, we don't publish a rating to Google's structured data.
- We don't scrape scrapable review text. Review counts and averages, yes. Individual review texts belong to Google.
- We don't sell score changes. Businesses can report factual errors, but payment cannot alter the formula or ranking.
- We don't hide the formula. Everything you just read is the entire algorithm. No AI black boxes, no secret weights.
